Question 157463
Remember: Square has 45 degress angle on the diagonal, since all sides are equal.
Then by Pyth Theorem., given diagonal=10 inches:
{{{sin(alpha)=opp/hyp}}}
given hyp=10" and {{{(alpha)=45deg}}}
{{{sin(alpha)=opp/10}}} cross multiply
{{{opp=sin(45)(10)=7.07inches}}}
ANSWER: A --------> {{{5sqrt(2)=7.07inches}}}
Thank you,
